This MotoSport guide walks you through safely flushing and bleeding the hydraulic brake system on your 2024 Yamaha Grizzly 700 4X4 EPS. Follow these steps to replace old fluid, remove air, and restore firm, reliable braking. Read all steps before you begin, and work methodically.
Important model notes — 2024 Yamaha Grizzly 700 4X4 EPS
- The Grizzly 700 uses DOT 4 brake fluid. Do not mix with DOT 5 silicone fluid.
- Brake master cylinders: front master is at the right handlebar (hand lever), rear master is actuated by the foot pedal assembly. Reservoirs are small & translucent on the masters; inspect fluid level before starting.
- Electronic Power Steering (EPS) has no direct effect on the hydraulic brakes, but always power the machine down completely and chock/wheel-block before working around steering components.
- Wear gloves & eye protection. Brake fluid damages paint & plastic — wipe spills immediately and rinse with water.
Tools & supplies
- Fresh DOT 4 brake fluid (quantity: roughly 250-500 ml depending on system flush method)
- Clear plastic tubing sized to caliper bleed nipples
- Catch bottle or jar (marked for contaminated fluid)
- Wrenches for bleed nipples (typically 8 mm or 10 mm)
- Vacuum bleeder, pressure bleeder, or second person for pump method
- Clean rags, small funnel, disposable gloves, safety glasses
- Service manual or torque wrench for reinstalling banjo bolts (if you remove lines)
Preparation
- Park the Grizzly on level ground, engage park/parking brake, kill engine, remove key. Chock wheels so it cannot roll.
- Clean the area around master cylinder reservoirs and bleed nipples to prevent contaminants entering the system.
- Remove reservoir caps & diaphragms carefully. Keep the reservoirs topped off during the procedure to prevent introducing air.
- Locate bleed nipples on each caliper — front calipers are on the front hubs, rear caliper at the rear hub.
Bleeding order
Always start with the caliper furthest from the master cylinder and finish with the closest. Typical order:
- Rear right (farthest)
- Rear left
- Front right
- Front left (closest)
Bleeding methods
1) Vacuum bleeder method (recommended for one-person operation)
- Attach clear tubing from the caliper bleed nipple to a catch bottle. Slide tubing over nipple and clamp if needed.
- Connect the vacuum bleeder to the reservoir or the bleed nipple per tool instructions. Do not overdraw the reservoir dry; keep fresh fluid available.
- Open the bleed nipple about a quarter turn. Apply vacuum and draw fluid until clear, bubble-free fluid appears, then close the nipple while vacuum is maintained.
- Top off the reservoir with clean DOT 4 fluid as needed between wheels to prevent air entry.
- Repeat for each caliper following the bleed order. Ensure all nipples are tightened to the correct snugness (snug & leak-free — avoid excessive torque). Wipe any drips.
2) Pressure bleeder method
- Fill the pressure bleeder with DOT 4 and attach it to the reservoir cap opening. Pressurize per tool instructions (typically low pressure, 10-15 psi max).
- Open each bleed nipple in order, letting fluid flow until clear and bubble-free. Close nipple before moving to the next wheel.
- Monitor reservoir level; never let it empty.
3) Two-person pump-and-hold method
- One person sits on the machine and gently pumps the brake lever/pedal to build pressure, holding the lever/pedal at mid-stroke.
- The helper opens the caliper bleed nipple to let fluid and air escape into a tube/catch bottle, then closes the nipple. Repeat pump/hold/open/close until fluid runs clear without bubbles.
- Top off reservoir frequently. Work in the bleed order from far to near.
Finishing steps
- When all calipers show clear, bubble-free fluid, tighten bleed nipples securely and replace reservoir caps & diaphragms.
- Clean any spilled fluid immediately. Dispose of old fluid responsibly per local regulations.
- Test brake lever and pedal feel with the engine off. Brakes should feel firm — if spongy, repeat bleeding.
- Perform a low-speed brake test in a safe area to confirm proper operation before riding hard or carrying loads.
Troubleshooting & tips
- If the system continues to feel soft after bleeding, inspect hoses, banjo fittings, and caliper seals for leaks or internal delamination that can trap air.
- Corroded or seized bleed nipples can be freed with penetrating oil and careful heat if necessary. Replace if rounded or leaking.
- If you remove brake lines or banjo fittings, replace copper crush washers and re-torque to Yamaha specs from the service manual.
- Do not let the reservoir run dry at any time. Air sucked into the system increases bleeding time and complexity.
Routine maintenance intervals
Brake fluid absorbs moisture over time. For riding conditions common to Grizzly owners — wet, muddy, or heavy-load use — MotoSport recommends inspecting fluid annually and replacing every 1-2 years or per Yamaha recommendations to maintain braking performance and prevent internal corrosion.
